Anita Mamtani, MD, of Memorial Sloan Kettering Cancer Center, discusses study findings showing that axillary lymph node dissection was required by less than 2% of patients with cT1NO triple-negative or HER2-positive breast cancer having upfront surgery. There was no clear advantage of neoadjuvant chemotherapy in reducing the risk of lymph node dissection in this cohort. Upfront surgery is a suitable approach in these patients, says Dr. Mamtani, allowing for de-escalated chemotherapy regimens in patients with pathologic node-negative disease. (Abstract P1).
Kari M. Rosenkranz, MD, of Dartmouth Health, discusses findings from the ACOSOG Z11102 (Alliance) study, which showed that breast-conserving therapy is safe for patients with multiple ipsilateral breast cancer lesions, resulting in low recurrence rates. However, omitting adjuvant endocrine therapy is a risk factor for recurrence. (Abstract 1).
Judy C. Boughey, MD, of the Mayo Clinic, discusses the decrease, over the past decade, of axillary lymph node dissection, especially in patients with node-positive breast cancer at diagnosis who had sentinel lymph node surgery after neoadjuvant chemotherapy. These findings are based on the records of more than 1,400 patients enrolled in the I-SPY2 trial. (Abstract 3).
In an analysis reported in the Journal of Clinical Oncology, Marion T. van Mackelenbergh, MD, PhD, and colleagues found that patients with early HER2-positive breast cancer who achieved pathologic complete response (pCR) on neoadjuvant chemotherapy plus anti-HER2 treatment had better overall and...

Lindsay L. Peterson, MD, of the Washington University, St. Louis, discusses the value of physical activity in improving cancer prognosis, especially for patients with breast or colon cancer. Aerobic exercises and resistance training are recommended during and after treatment. Exercise may help inhibit tumor growth, improve quality of life by decreasing fatigue and anxiety, build muscle mass, increase physical function, and reduce surgical complications and treatment delays.
Patients who underwent pathology evaluation of their sentinel lymph nodes during mastectomy surgery may have been significantly more likely to receive aggressive nodal therapy than patients whose lymph node biopsies and treatment strategies were evaluated after surgery. The new findings were...

On March 3, 2023, abemaciclib was approved for use with endocrine therapy (tamoxifen or an aromatase inhibitor) for adjuvant treatment of patients with hormone receptor (HR)-positive, HER2-negative, node-positive early breast cancer at high risk of recurrence.1 Abemaciclib was previously approved...
Here is how Dr. Sharma summed up the current state of neoadjuvant therapy in triple-negative breast cancer: The addition of an immune checkpoint inhibitor to neoadjuvant chemotherapy improves long-term outcomes. This strategy can produce a modest improvement in pathologic complete response and a...
Although advances in radiation therapy have rendered this treatment modality more tolerable, they have not completely eliminated the burden of radiation-related toxicity. In an ideal setting, clinicians would be able to identify patients whose risk of recurrence is sufficiently low that they can...

Breast cancer screening and imaging-based surveillance after treatment remain suboptimal, largely because of confusion in the guidelines and the fact that dense breasts are too often ignored, according to Elizabeth Morris, MD, FACR, FSBI, FISMRM, Professor and Chair of the Department of Radiology...
Matthew P. Goetz, MD, of Mayo Clinic, discusses recent data from the MONARCH 3 trial of patients with advanced hormone receptor–positive, HER2-negative breast cancer. The study, a second interim analysis, showed that longer overall survival was observed in both the intention-to-treat group as well as in the subgroup with visceral disease. However, neither met the threshold for statistical significance, and further analyses are planned when more data can be reported. (Abstract LBA15).
